Kayl is a unique and contemporary unisex given name, derived from the Welsh male name Cael. It signifies 'harmony' or 'consonance', reflecting its origins in the Welsh language. The name has gained popularity due to its modern sound and flexibility, as it can be used for both boys and girls. Kayl is often associated with creativity and individuality, perhaps due to its unconventional spelling and pronunciation.
"Kayl gained popularity as a baby girl name in the late 1980s and early 1990s with peaks in 1997 and 1998, then experienced a significant rise again around 2006-2009, and has since had fluctuations but remained relatively popular up until recently."
